История изменений

Кщё как выяснилось Rust ещё и не свободен, за модификации языка и рантайма могут засудить:

Uses that require explicit approval

Distributing a modified version of the Rust programming language, compiler, or the Cargo package manager with modifications other than those permitted above and calling it Rust or Cargo requires explicit, written permission from the Rust Foundation. We will usually allow these uses as long as the modifications are (1) relatively small and (2) very clearly communicated to end-users.

Делать несовместимые версии Си никто не запрещает и их реально делали например Borland и Microsoft.
